To. all 'whom t may concern Be it, known that I, GEORGE IV. NEWMAN. acitizen of the United States, and a resident of the city of Chicago,inthe county' of Cook I and State of Illinois, have invented certain newand useful Improvements in a Ring- Book Lock; and I dohereby declarethat the following is a full, clear, and exact description of the. same,reference being had to the 1.1! accompanying drawings, and to thel'numerals of reference marked thereon, which form a part of thisspecification. Y

This invention relates to a ring book of that type involving rockable ortiltable book l carrying members, which maybe tilted upwardly to opent-he rings or tilted downwardly for closing the rings. A

' This invention concerns` itself primarily l with means for locking thebook carrying members ineitherof their tilted positions v1n order thatthe ring book may be locked in either open or 4closed position. n

The invention comprises the novel'structure and combinations hereinafterdescribed and more particularly .pointed out vand defined' in theappended claims.

In the accompanying drawings which illustrate a preferred embodiment ofthis invention and in which similar reference numerals refer to similarfea-tures in the dierent views,

Figure 1 is a to-p plan View of a ring book involving this invention.

Figure 2 is an enlarged fragmentary transverse sectional view throughthe ring book.

Figure 3 is an enlarged view similar to Figure 2 but showing the ringhooks in open position.

Figure 4 is an enlarged fragmentary top plan View of the loose leafholding mechanism showing the locking means.

Figure 5 is an enlarged fragmentary longitudinal sectional view throughthe lower t5 part of the ring book.

Figure 6 is an enlarged trans/erse sectional view through the leafholding mechanism showing an alternate form of the nvention. Figure 7 isan enlarged fragmentary longitudinal sectional view upon the line 7-7 ofFigure 6.

Figure 8 is a bottom plan view of Figure 6. In referring now to thedrawings, espetends.

cially to Figures 1 to 5, it will beV observed that the binder generallyconsists of-a back 1 and covers 2 which are hinged to the backi A housedresilient plate '3 having a depression 4 is suitably secured inter-iorlyof the back and provided with marginal lips' for i retaining therockab'le or tiltable hook carry ing plates or members 5. The abuttingedges of these plates4 5 are loosely connected l for conjoint tiltingmovement by means of studs 6, so thatV they function somewhat in themanner-of a toggle.

An apertured washer or cap 7 is secured in the depression 4, the centralpart of this washer 1s upwardly offset to provide a space for rotatablyreceiving the hea-d8 of ay lock- Vhead 1,0v `may pass when properlyalined.

Above the. key hole yslot 11, the'v cover plate u V13 of the'leafholding mechanism is f proj vided with a suitable aperture 14 forreceiving a key. The hook carrying plates are alsov preferably providedwith stop members 15 to `limit the rotation of the stud 9 in bothdirections so that the locking head may be brought-to a stop in` lockingand unlocking positions.

In Figures 6, 7 and 8 the bowed plate 8 is, provided with a depression16 through which a slot 17 extends. The locking stud 18 in this form hasan elongated head 19 which is designed to pass through the slot 17 whenthe same is properly alined therewith. However,- when the same ispositioned transversely of the slot it serves to lock thev toggle plates5 from being tilted upwardly.

The i The upper part of the stud 18 is provided with a pair of spacedcollars 20 and 21 which overlap the upper 'and lower surfacesof thetoggle plates through which the stud ex- The upper end of this stud 18Visr likewise provided with a key hole slot for receiving a key which maybe inserted through a suitable aperture 14 in the cover plate 13. A pairof stops 22 are preferably provided in the depression 16 for limitingthe rotation of the locking stud 18 to locking and unlocking positions.

rIhe locking stud in either vform is adapted to be rotated to lockingand unlocking position by a suitable key. When the locking head has beenrotated to the position shown in Figures fl and 8 the ring holdingmembers are in locked position against upward tilting movement. However,when either stud is rotated to bring the locking head in alinement withits slot, it will pass therethrough and allow upward tilting movement ofthe ring holding members. If it is desired to lock the ring hooks inopen position, the locking stud may'be rotated to bring the locking headthereof in a position transversely of the slot to preclude the same frompassing therethrough as is obvious.

I am aware that numerous details of construction may be varied through awide range without departing from the principles of this invention, andI therefore do not purpose limiting the patent granted otherwise thannecessitated by the prior art.

I claim as my invention:

1. In a ring book, a pair of toggle plates, a bowed plate for retainingthc same for conjoint tilting movement, and a releasable .memberconnecting said toggle plates and bowed plate.

2. In a ring book, a pair of toggle plates, a bowed member for retainingsaid toggle plates for conjoint tilting movement, and a rotatabledevicereleasably connecting said plates and member. f

3. In aring book, a pair of toggle members, a bowed member for retainingsaid toggle members for conjoint tilting movement, and a memberconnecting said members and bowed member, and rotatable for severing itsconnection with one of said members.

il. In a ring book, hook carrying members, means for retaining the samefor limited movement, and a device for locking said members in closedposition.

5. In a ring book, hook carrying members, means for confining the samefor limited movement, and a device having limited movement and inengagement with said members for locking the same in a predeterminedposition.

6. In a ring book comprising tiltable hook carrying members, a bowedmember for retaining the same for conjoint tilting movement, and a studhaving means for connecting said tiltable and bowed members, andoperable for disconnecting the same.

7. In a ring book comprising hook carrying members having limitedmovement and a manually operable member for locking said first membersat one limit of movement.

8. In a ring book comprising rockable hook carrying members, a resilientmember for retaining the same, a locking stud connecting said hookcarrying members and resilient member and rotatable for releasing one ofsaid members, and means for limiting the rotation of said member.

In testimony whereof I have hereunto subscribed my name.

GEORGE W. NEVVllIAN.
